Consider a sample of oxygen behaving like an ideal gas. At $\displaystyle 300$ K , the ratio of root mean square (rms) velocity to the average velocity of gas molecule would be :
(Molecular weight of oxygen is $\displaystyle 32 \mathrm{~g} / \mathrm{mol} ; \mathrm{R}=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ )
Official answer
(1)
$\displaystyle \sqrt{\frac{3 \pi}{8}}$
